LIFTING APPARATUS;

Application filed April 4, 1924, Serial No. 704,178.

To all whom it may concern.

Be it known that WGYGEORGE 0. Home and PETER ENDRES, citizens of theUnited States, residing at Chilton, in the county of Caliunet and Stateof-l Visconsin, have in-' vented certain new and useful ImprovementsinLifting Apparatus, of which the following is. a specification.

This invention relates to apparatus for use in hospitals for raisingpatients from their beds so that their bedding can be changed, and forother similar purposes; and it consists of a portable framework and aframe provided with bands-of flexible material for supporting thepatient and raising him above his bed. as hereinafter fully describedand claimed.

In the drawings, Figure 1 is a side view of an apparatus constructedaccording to this invention. Fig. Qis an end view of the same lookingfrom the left in Fig. 1. 3 is a plan side view of the end portions ofone of the bands of flexible material, and is drawn to a larger scale.Fig. 4 is a plan view of the same.

The portable framework has a horizontal bar 6 at its top of sufficientlength to extend longitudinally over the bed in which the patient isresting. The ends of the bar 6 are connected to vertical members 7 byquarter bend pieces 8, and all the framework is preferably tubular forlightness and The vertical members '7 are socured and braced to the endportions of a rectangular frame 8' arranged horizontally and providedwith legs 9 which rest on the floor. The framework is proportioned sothat it can be stood over the bed and the patient in it, and so that itcan be moved about from bed to bed with great facility.

A rectangular main frame 10 is provided, of greater length and widththan the body of the patient, and is adapted to be placed over him as helies in the bed so that it rests on the bed around him. An auxiliaryframe 12 15 arranged 1ns1de one end por tion of the main frame. and oneend of it is horizontal top bar 6. The lifting tackles are preferablyself-supporting tackles provided with straps,-instead of the usual.cords, but any approved lifting devices may be used. Separate liftingdevices '15 are provided so that each end of the frame can be raised andlowered independently of the other. j 1 Y j I The main frame -10 and theauxiliary frame 12 have pins 18 which project upwardly from their sides,and 20 are bands of flexible material, such as canvas, which are adaptedto be passed underthe body of the patient and sustain him in the frame.

A hoisting tackle 21 is also secured to the top bar 6 and to the freeend portion of theauxiliary frame, so that it n'iay be supported at anysuitable angle withthe hori- V ontal main frame 10 to suit the head andshoulders of the patient.

Each band'20 has a fastening plate El i at one end having a hole 25 forengaging with one of thepins 18," and each plate. has also a long slot26.-- The end portion of the band is passed downwardly through the slotand is looped around an anchor rod 27, and is then folded double and ispassed upwardly through the slot. The band is adjusted in length byarranging the rod 27 at different distances from its extreme end. As thedoubled portion 28 is pressed on the plate by the weight of the patienton the upper stretch oft-he band, and asthe rod 27 is longer than theslot, the band cannot slip after being adjusted in length.

The other end portion of the band is provided with a fastening plate 30similar to the plate 24, and it has a similar hole'and slot, and'isconnected to the band by a similar anchor rod. A loop-shaped handlemember 31 is pivoted in an eye 325011 the outer end of the plate 30, andis used for drawing the band taut, and connect ing the plate to its pin.The lever. '31 is passed under the body of the patient and over the sidebar of the frame, and is then pressed downwardly in contact with the baruntil the hole in the plate slips over the pin. In Figs. 3 and 4thehandle member is shown in a raised position for clearness ofillustration. When the handle member is slid under the patient and ontothe side bar of the frame its loop clears the pin'S. The free endportion of the handle member 31 is then pressed downwardly under andagainst the frame bar, so that it operates as a lever having theframebar as a fulcrum.

The handle member slidesron the frame bar and draws upon the band 20until the hole in the plate 30 slips over the pin 18', both plates 24and30 being at that time substantially horizontal and theband 20 taut. The

7 plate 30 is raised a little by hand, if neces tackle, and the wholeapparatus is slid clear of the bed, the patient may be supported at anangle to the horizontal, as well as horizontally, which is sometimesdesirable.

The apparatus is subsequently replaced over the bed, and'the patient islowered onto it. This use of this apparatus saves badly injured patientsfrom much pain and discomfort. V

What we claim is: V

1. In an apparatus for raising and supporting patients, a mainframework, a frame for the patient provided with pins which projectupwardly from one of its sides, bands of flexible material provided withmeans for connecting them to the other to the free ends of the endplates and adapted to be used as levers, with the frame bar as a fulcrumfor drawing the bands tautand slipping the holes of the end plates overthe pins, and lifting devices supporting the said frame in the mainframework.

2. An apparatus as set forth in claim 1, the said end plat-eshavin eyesat their free ends, and the said handle 'members being loop-shaped andbeing pivoted in the said eyes. 7

3. In a frame for supporting a patient, side bars one of which hasupwardly projecting pins, bands of flexible material jprovided withmeans at one end for attaching them to the other side bar of the frame,plates connected to the other ends of the flexible bands and havingholes for engaging. with the said pins, and handle members pivoted tothe said'plates and formed of rigidmaterial and adapted to be used aslevers, with the frame bar as afulcrum, for drawing the flexible bandstaut and slipping the said holes over the pins,

In testimony whereof we aflix our signatures.
